Powertrain Options That Mean Business 

The 2026 GMC Sierra 2500HD offers two proven powertrains, both built for demanding workloads. The standard 6.6L V8 gas engine produces 401 hp, giving you reliable performance for everyday hauling and towing. 

For those who need more pulling power, the available Duramax® 6.6L Turbo-Diesel V8 delivers 470 hp and 975 lbs. ft. of torque. That kind of torque is what makes the difference when loads get heavy and conditions get tougher. 

When properly equipped, the Sierra 2500HD can tow up to 22,390 lbs. That is the kind of capability that supports job sites, equipment transport, and weekend hauling without hesitation. 

Technology That Supports the Workday 

Technology in the 2026 GMC Sierra 2500HD is designed to make the job easier, not more complicated. The available 13.4-inch touchscreen provides clear access to navigation, trailering tools, and smartphone integration. Everything is laid out in a way that is easy to use, even during a busy day. 

Safety and driver assistance features are built in to help reduce stress behind the wheel. Available systems include Forward Collision Alert, Lane Departure Warning, and a Surround Vision camera system that improves visibility when maneuvering in tight spaces or around equipment. 

Practical Features That Earn Their Keep 

The Sierra 2500HD is built with details that matter when the work starts. The available MultiPro™ tailgate offers six different functions, making it easier to load, unload, and access the bed. It is the kind of feature that proves useful quickly once you put it to work. 

Inside, the cabin is designed for long hours. There is plenty of space to stretch out, along with durable materials that hold up to daily use. It is comfortable enough for extended drives while still being tough enough for a work environment.
